In early 2025, a groundbreaking discovery in the field of microscopy captured the attention of researchers worldwide. The unveiling of the world’s first fully 3D-printed microscope sparked immense interest due to its rapid production time and significantly reduced cost.
Lead researcher Liam Rooney from the University of Glasgow revealed that the innovative microscope garnered widespread acclaim following its feature in New Scientist. The project received inquiries from diverse sectors including biomedical research, community organizations, and even filmmakers. The research findings were officially published in the Journal of Microscopy.
The microscope’s body was constructed using a design sourced from OpenFlexure, an open-access platform for 3D-printing scientific instruments. By incorporating a store-bought camera, a light source, and a Raspberry Pi computer for control, the research team achieved a cost-effective and accessible microscope solution.
Notably, the team’s breakthrough involved the 3D printing of the microscope’s lens using clear plastic. This advancement significantly reduced the overall manufacturing cost, making the new microscope available for less than £50.
Team member Gail McConnell from the University of Strathclyde highlighted the unprecedented interest from lens manufacturers in the team’s work. The affordability and lightweight nature of the 3D-printed lenses presented a novel opportunity in large-scale manufacturing. The microscope’s capabilities were validated through the examination of blood samples and mouse kidney sections, showcasing its potential for medical and biological research.
Driven by a vision to democratize access to microscopy, the team has embarked on collaborations with the Kwame Nkrumah University of Science and Technology in Ghana to enhance research and educational opportunities in West Africa. With support from the UK Institute for Technical Skills and Strategy, the researchers are actively involved in initiatives aimed at empowering students facing educational barriers.
Furthermore, the integration of the 3D-printed microscope into the Strathclyde Optical Microscopy Course signifies a transformative shift in educational practices. Ongoing efforts to enhance the microscope’s resolution and contrast without escalating costs reflect the team’s commitment to continuous innovation.
McConnell emphasized that the future potential of the 3D-printed microscope hinges on advancements in 3D-printing technology. As consumer electronics and 3D printers evolve, so will the capabilities of the microscope. The team remains dedicated to pushing the boundaries of innovation and expanding access to cutting-edge microscopy tools.
